Doulkus Pontikis - if you're referring to 2.02c, I can expand on what you're finding. Note also that the recruitment changes have been applied to the development build too, they will be in the full summer release.

Pontos are considered a Hellenistic faction. Therefore you don't get phalangites of any kind easily. Just like the other Hellenistic factions, they get no Hellenistic/Greek units out of their factional government buildings - they need a Polis or Colony building. Try Pergamon or Epeiros or Makedonia or Bosporans or Ptolemaioi or Seleukids (or even Koinon Hellenon) - you'll find the same thing. It's an intentional change to the way they recruit which adds to the challenge and makes them different to playing other factions.

If you want Pantodapoi Phalangitai, you have to build a native garrison (Phourion Laon). They are the "eastern phalanx", by the way, there are no plans to create a separate, special phalanx unit for eastern kingdoms. The native garrison isn't intended to be useful everywhere - it has no pools in Greece or Galatia, which is why you're finding no options there. In those places you need an Allied Government if you want troops quickly.

As to the roster, yes it's a bit thin at the moment. We do have some concepts for new units, and there'll be some placeholders in the full release for customised units that will come later, so at least there will be more functionality in the roster. Chalkaspides are in the summer release - remember the tweet about Elite Phalangitai? Pontic Chalkaspides are one of those. Kataphraktoi are coming, too.

On province changes, still an ongoing discussion backstage.
